PROBLEM TO BE SOLVED: To increase a player's motivation to play a game.SOLUTION: In a game machine, a game progresses under a game state which is set to either a low probability game state, in which a big winning result is derived according to a low probability determination condition, or a high probability game state, in which the big winning result is derived according to a high probability determination condition that derives the big winning result with a high probability. When a start condition is established in the low probability game state, the big winning result is derived according to the low probability determination condition. When the start condition is established in the high probability game state, the big winning result is derived according to the high probability determination condition. If a big role game is executed by controlling the opening/closing of a big winning port on a condition that the big winning result has been derived, the game state after the completion of the big role game is set to the low probability game state or the high probability game state. If a game ball enters a specific area at least within a predetermined period of time before the execution of the big role game, the game state after the completion of the big role game is set to the high probability game state.SELECTED DRAWING: Figure 36 |
